' o all whom 'it may concern:

Beit known that I, FREDERICK C. NIcKoL, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new f and useful Improvements in Flushing Apparatus for Water-Closets, and I do declare the followingr to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to 'which it appertains to make and use the same.

My invention relates to ushing apparatus for water closets, and particularly to that type of apparatus which is automatic in action.

The object of the invention is to provide a device of this character which is cheap to construct and positive in its operation and withal of-such formation as will occupy comparatively'little room and will present a neat appearance.

A further object of the invention is thel provision o f means which positively regulates the amount of water which is to be ted to the closet at each iushing and at the same time to feed the Water thereto under pressure.

A still further object of the invention is the provision of means for automatically placing the water feeding means into opera-- tive position upon the use of the clot, and

to cutod simultaneously the water thereto4 until the weight and further to ho a predetermined length of time and 'to automatically release it. l

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed` out in the appended claims.

In the accompanying drawings, Figure 1 u on the seat is removed, l

is a side elevation showing the relation of the operating mechanism with the closet bowl, Fig. 2 is a vertical longitudinal seei tion, Fig. 3 is a top plan view, Fig. 4 is` a horizontal `Section laken on the line44 of F ig. 2, Fig. 5 is a vertical sectional view taken on the line 5-7-5 of Fig. 2.

Referring more especially to the drawings, 1 represents the closet bowl, and 2 the seat which is pivoted upon the upstanding lugs 3, as is usual and is provided upon its under side with a valve operatin f arm 4, to be hereinafter described.' The eoset bowl in the inlet valve open for this instance is provided with ay rearwardly extending coupling member 5, to which the closet union 6, is secured by screw threads orother suitablemeans. The reduced member of the union has attached to it a connecting device 7, provided with a central bridge piece, extending across the connection and centrally apertured so as to receive the vaive rod 9, of the shut oli' valve 10. Beyond the bridge piece the connection is somewhat enlar ed to 'receive the threaded and reduced en 11, of the exit valve coupling 12, which is threaded to the valve neck 13, carriedl by the casing 14, and having its outer part ground to'form a valve seat. At the opposite end of the casing a valve neck 15 isprovided which is connected by a couplin 16, with the water supply pipe 17.l This valve neck 15 leads up into the casing vand has forming an integral part thereof the discharge nozzle 18, which will be herey inafter described. Slidably mounted within..

the casing 14 is the inlet valve rod 19, carrying upon its lower end the valve 20, provided with a rubber gasket adapted to engage the inner side of the valve neck 15 upon which it is normally seated by the action of the sprin is limite( in its movement by a pin and washer, as is usual. The upper end of the rod passes through the stuffing box 22, in the top 23, and'is en aged at its upper end by a lever 24, which 1s pivoted intermediate its length upon a standard 25, carried by the casing so as to depress the valve rod 19 and valve 20 when actuated by the arm 26, carried by the rear end of the seat and slotted at 27, to enoage the pin 28, upon the forward end of the lever 24. The exit valve rod 9 extends through thebridge pieces 29 and 8 and into engagement with the arm 4 of the seat, and a spring 210, which surrounds the shaft i) and abuis thc-bridge piece S at o'ne end and a washer 31 al the other end, which is held in position by a transverse pin 32, forces the rod outwardly and raises the seat throu h its action on the arm-4, slightly above tic edge ot' the board upon which it rests when the closet is being used at the same time the valve l() is held offis seat. This action of course depress-es the arm 26 and allowsthe spring 21 to force the valve 20 into engagement with its seat and close the inlet. l/Vhen the closet is beingfl used the weight upon thel 21, which surrounds the rod and "quently the valve rod 19. This action carries the valve 20 oif its seat and permits the water to flow through the nozzle 18 into the water canal In order to hold the valve in this posit-ion I provide a mechanism which shall now describe. The top plate 23 is provided with a pair of depending side members or plates 34, in which is journaled a shaft 35, carrying intermediate its length the pawl 36, which is weighted at its outer end to normally force its forward end 36 into engagement with a notch 37, formed in the rod 19. As the valve is depressed by the action of the lever 24 which is controlled b y the Weight upon vthe seat, the forward end of the pawl 36 falls into the notch 37 and holds the valve 2O off its seat. This condition of affairs would permit the Water from the inlet supply pipe 17 to continue to run after the seat had been vacated and the valve '10 'carried off its seat by the spring 30, In

order to limit the amount ofwater supplyto the nozzle I journal ashaft 38 between the plates 34 and key thereto a water wheel 39, having a plurality of arms extending down into the path of the water in the canal Adjacent the wall I provide a bevel gear 40, which meshes with a similar gear 41, carried upon the short shaft. 42, which is journaled in brackets 43. Between these brackets the shaft is provided with screw threads 44, which engage'with a worm gear 45, carried upon the transverse shaft 46, also journaled between the plates 34. rlhis worm gear 45 has mounted upon its side a Wheel 47, which is provided with a cam lug 48, adapted to engage the underside of the pawl 3G so as to release it from the notch 37.

ln order that the operation of the device may be better understood it will be stated that when the closet is'occnpied the arm 4 is necessarily pressed against the valve rod 9, thus closing the valve 10 and :at the same time the arm 26 is operated to control the lever and open the valve '20. rlhis prepares the device for the operation. of the Hush which is started immediately that the seat is vacated. 'lVhen this is done the seat is raised under the tension of the spring 30, which at the same time releases the valve 10 and the arm 2G is depressed allowing the spring 21 toforce the valve 2O to its seat. But owing to the fact that the pawl 3G is in engagement with the notch the valve is held open and the pin 28 slides, idly in the slot 27. The water continues to pass through the nozzle 18 and act upon the water wheel to give ita predetermined number of revolutions. Preferably a Worm gear is used, constructed so that it will make one complete revolution for every nine revolutions of the water wheel.

`closing said inlet valve.

series As the cam lug 48 reaches the under side of the pawl 36 its'rear end is tilted on the slial't and releases it from the notch 37. thus allowing the spring 2O to close the valve 'l0 upon its seat and ent oil' the water supply. From the foregoing description, taken in connection with the accompanying drawings, the construction and operation olE the invention will be readily understood without requiring a more extended exlgilanation.

Various-changes in the i'orm, proportion and the minor details of construction may be resorted to without departing `from the principle or sacrificing any of the advantages ot this invention as defined in the appended claims.
